Seeds) ผู้เขียน: Panie Temiesagdie, Taikichi Takano, Prateung Donsomprai สื่อสิ่งพิมพ์:pdf AbstractThe new harvested cucumber seeds, local varieties often fail to germinate, because of dormancy. It take over 5-6 storage months until dormancy phenomenon disappear. The hot dry air treatment at 60o, 65o, 70o, 75o or 80oC for 1 to 7 days or 90oC for 1 to 24 hours could break that dormancy. Dry heat treatment at 70oC for 3 days obtained the best result. This treatment could up grade in germination from the initial 20% and proved good growing characteristic in either vegetative or generative organs as near as untreated seeds. Further more, soaking cucumber seeds in warm water at 45o, 50o, 50o and 60oC for 20-60 minutes has been done for breaking seed dormancy. Soaking seeds at 60oC for 40 minutes show that results among hot wet treatment, but it still was not better than hot dry air treatment at 70oC for 3 days. |
